Development and Performance of High-quality 1.2367 Steel

摘要: 试制了截面尺寸为220 mm×810 mm和Ø220 mm的两种规格1.2367热作模具钢，研究了试验钢在不同淬火、回火工艺下的硬度变化和硬度范围46~48 HRC时试验钢的冲击韧性和拉伸性能。结果表明：试验钢回火二次硬化峰值温度为510℃，峰值硬度为56.5 HRC，经1 050℃淬火+620℃回火后其心部等向性达到90%左右，其中扁钢心部横向无缺口冲击功达到371 J；1.2367钢与H13钢相比，可应用于更高的使用温度范围，有更高的强度和冲击韧性。

Abstract: Two types of 1.2367 steel 220 mm×810 mm and Ø220mm were developed. The hardness of the test steels under different quenching and tempering processes and the impact toughness and tensile properties in the range of 46-48 HRC hardness were studied. The results show that tempering secondary hardening peak temperature was 510℃ and the peak hardness was 56.6 HRC, the isotropic in the center of test steels reach to 90% after quenching at 1 050℃ and tempering at 620℃, the unnotched impact energy in the transversal direct and center of the 220 mm×810 mm size test steel reach to 371 J. 1.2367 steel has the application of higher temperature range and has higher strength and impact toughness compared with H13 steel.
